The schematics:
It should convert 0-3.3V input from the DAC to -4.1 + 4.1V (roughly)
The positive part works great, the negative output voltage saturates at -2.95V.
Is it ok? The simulation looks ok (and it is the expected behavior):
Electronic – OPAMP saturating when output is negative, simulation is OK

Yup. If you look at Figure 2 of the data sheet, it shows a nominal maximum for +/- 5 volt supplies to be 6 volts pk-pk. In other words, about +/- 3 volts, and you're getting -3. Just about what you'd expect.
The positive side is doing better than expected, but that's just an unexpected bonus.
TL;DR - You should never count on getting +/- 4.1 with your power supply and this op amp.
